System constructor keyword argument load_zone_formatter is ignored

[GabrielKS]

There is a kwarg load_zone_formatter listed as one of the supported SYSTEM_KWARGS:

PowerSystems.jl/src/base.jl

Line 13 in 71b9bf4

:load_zone_formatter,

but, unlike all the other SYSTEM_KWARGS, nothing is ever done with it. This is the only reference to it in the codebase. I'm currently in a situation where I need to remap the names of load zones, so it would be nice to support this behavior as we do for buses, generators, branches, etc.

good first issue because if all we need is a name formatter I think it could be implemented pretty similarly to the existing ones

@GabrielKS What do you need to do here? The main problem is that powerworld does not create a zone dictionary. The load zones are created manually based on the information in the bus dictionary in bus["zone"] key. Would be tricky to pass a function is that we don't have access at the moment of creation of any additional data x that we can do something.

@rodrigomha my use case is here — I am creating a System from a PSS/E .raw file and adjusting a bunch of names based on a JSON that gets written alongside the .raw by the new Sienna PSS/E exporter. All I need is the ability to pass in a mapping from what Sienna thinks the name should be to what I actually want the name to be and have that be evaluated.
